HEATER non wavrne HAIR.

Application filed July 11, 1923.

My invention relates to heating devices which are adapted for use in the art of waving hair, and the improvements are especially applicable to heaters which are now used so extensively in the process of waving natural hair on the head of the subject, and which derive their heat from an electric current. In using these heaters, the hair in strand form is wetted and then wound around a rod in helical turns and is then covered or not with absorbent material and inserted within the bore of the electricheater, after which the current is applied for several minutes and until the heat is run up to quite high degree, generally to the boilin point. Under this condition the heater body becomes too hot to be grasped directly in the hand of the operator who has to manipulate the heater and remove it. In this process, the head-end of the heater is usually provided with a closure for aiding the process and also for keeping the.

vapors and heat away from the scalp of the subject and heat insulating or protecting means are often used. My present invention provides hand grasping means or handles for the heater which are kept from becomin highly heated; also means for detachab y applying a closure to the head-end of the heater, as well as means for protecting the head or scalp of the subject from the heated end of the body of the heater. Other provisions are also made by my present improvements which will appear in the description hereinafter given.

I have illustrated an embodiment of my inventions in the accompanying drawings, wherein;

Fig. 1, shows a side elevation of my improved heating device, with the closure applied to the head-end thereof and in closed position and with the combined handles and gripping means in clamping engagement with the said closure.

Fig. 2, shows a side elevation of the same, taken at right-angles to the view in Fig. 1.

Fig. 3, is a similar view to that shown in Fig. 1, with the resilient handles or grasps pushed inwardly towards the shell to release the gripping jaws from the closure, the latter being removed.

Fig. 4c, is a cross-sectional view of the device, the plane of the section being indicated by lines 4-4, in Fi 1.

Fig. 5 is an end view 0 the closure shown as detached.

Fig. 6, is a cross-sectional view ofthe device, showing a modified form of the retaining band and sliding connection between the same and the resilient handle members.

Referring to the drawings, 1 indicates a tube open at both ends and provided near the head-end with. a surrounding casing 2', within which is arranged the usual electric heating coils which need not be-here illustrated, the said parts 1 and 2 being secured together. This structure is the ordinary one used so generally in the process of permanent waving of natural hair on the head of the subject, an electric-wire being connected with the structure to furnish the heatin current and the structure being suspende overhead by suitable means, not shown,

Serial No. 650384.

groups of two or three dozen being so ar-' ranged as often that number are used for waving the hair of the subject.

For this structure, I provide a simple and etlicient hand-grasping means which retains comparatively little of the heat of the attached body part or shell, said means at the same time serving as clamping means for the closure which I apply to the head-end of the device. At the outer end of the tubular structure distant from the head-end, I mount a collar 3, by means of a pin t, and to this collar Isecure by screws 5, the respective ends of the hand-grasps 6 and 7, which are made of resilient material in strip form and are constructed alike. These arms or handles 6 and 7, extend longitudinally of the shell structure and practically the length so as to lie diametrically opposite each other. The arms are bowed or bent outwardly from the shell as at 8, and near the head-end they are bent sharply inwardly as at 9, for the reception of a loose retaining band or ring 10, which surrounds the arms and keeps them close to the exterior of the shell, at the same time to permit of the arms having an endwise movement with respect to the shell, when the arms are pressed inwardly towards the same, the band 10, at such time moving with the arms, as indicated in Fig. 3.

The free ends 11, of the arms 6 and 7, which lie at the head-end of the body member of the heater, form clamping jaws for engaging and clamping the inwardly extending project-ions 13 and 14, on the closure 15, which is detachably mounted upon said end of the device. The extreme ends of the spring-arms or bars 6 and 7, are rolled .dle 20 and the member 18, having a handle 21, so that they together form somewhat of an X-shaped structure. The opposing edges of the members 17 and 18, are formed with corresponding notches 22 and 23, which when the members are closed rovide an opening 2 1, for the reception 0 the curler rod 25, and the wound hair 26, as indicated in Figs. 1, 4 and 6. The outer ends of the two closure members are kept together when closed, by means of the end of blade 18, taking into a groove formed by the bent-over ear 27, on the end of blade 17 and this arrangement serves to maintain the adjacent faces of said plates in close contact, as shown in Figs. 2 and 5. A spring 28, carried by the pivot 19, of the blades, lhasits respective ends in engagement with the finger pieces or lugs 29 and 30, on the ends of the respective handles 20 and 21, of the closure plates 17 and 18. This spring acts to normally keep the handles apart and the plates closed, as shown in Fig. 5, and when the two handles are pressed together by the fingers of the operator, the closure plates are opened so that they may then be placed over the head-end of the heater shell, whereupon the releasal of said handles causes the spring to come into play and clamp the said plates 17 and 18, against the exterior of said hair. The closure is'also clamped in suspended position against the end of the shell or body part, by meansof the jaws 11, 11, on the free ends of the arms 6 and 7, said jaws engaging the outside of the inwardly projecting pieces 13 and 14, of the closure, as hereinabove described. The bars 6 and 7, being formed of resilient material and being held near the said jaws by the retaining band 10, exert a spring clamping action on said jaws which is imparted to the projections engaged thereby.

The head-end of the heating shell is provided with a protecting-cap 31, made of felt or suitable fibrous material and fitted snugly over the end of said shell so as to extend well down on the exteriorthereof and also to cover the end of the same, the closed end of said cap being formed with an orifice 32, for permitting the curler rod with the wound hair thereon to extend through the ca into the interior of the shell. This su stantially large felt cap serves to protect the head of the subject from the heated end of the shell and to that extent increases the comfort accompanying the use of the device.

In Fig. 6, 1 show a modified form of the tion, the band is circular in plan as at 10,

and at' opposite points is provided with recesses or bends 33 and 34, for the reception of the respective bars 6 and 7, which slide therethrough.

In using the device, the strand of hair 26, being wound on rod 25, and tied thereto in the usual way and the hair wetted and, if preferred, wrapped in-wetted absorbent material, then placed in a steaming-tube and this assemblage is inserted in the interior of the heating shell, the side handles 6 and T, of which are grasped in the hand of the operator and pressed together so as to open the jaws 11, 11, whereupon the closure is applied by pressing together its handles and opening its plates so as to pass them around the wound strand of hair and place the inner face of the same in contact with the felt covered end of the shell.

bars 6 and 7, are released and the jaws thereof close against the projections on the closure plates and hold them as shown in Figs. 1 and 2. The electric current is then applied and the process carried out as above stated. 7

The combined hand-grasps and clamping means in the form of the resilient strips 8, provide a surrounding cage-like structure, which is kept comparatively cool because the heat from the heater cannot well be conveyed to it and in addition to having the lateral movement relatively to the body of the heater when grasped and squeezed, it also has an endwise creeping movement on said body.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:
